Grid Storage System with Deployable Partitions for Fire Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage systems with stacked containers in grid structures face challenges in efficiently isolating affected areas during catastrophic failures, leading to costly shutdowns and damage from sprinkler deployments, and lack flexibility in managing temperature and gas environments.
Innovation Solution
A storage system with a grid framework and deployable partitioning means beneath the grid level, allowing for separate sealing of sections, integrated services like water and sensing systems, and collapsible walkways to manage emergencies and environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the storage system uses a dense grid structure with stacks of containers, then storage density and space utilization are improved, but the ability to isolate affected areas during catastrophic failures deteriorates
Solution Approach 1:
The storage system is divided into multiple independently sealable sections by partition means positioned between stacks. Each section can be isolated from others using deployable partitions that create separate compartments, allowing fire or damage containment to specific areas while maintaining operational status in other sections.
2Reliability
If deployable partition means are added to enable area isolation, then reliability and safety during emergencies are improved, but device complexity increases
Solution Approach 1:
The partition means are designed to be deployable rather than fixed, allowing them to be stored compactly during normal operation and deployed only when needed for isolation. This dynamic approach reduces space requirements and simplifies the overall structure while maintaining the capability for emergency area segmentation.
3Object-affected harmful factors
If the system incorporates partition means for isolating sections, then damage from sprinkler deployments and catastrophic failures is reduced, but manufacturing complexity and cost increase
Solution Approach 1:
The partition means create separate sealable sections within the storage system, preventing sprinkler water and fire damage from spreading across the entire system. Each section can be independently sealed off, limiting the scope of damage and reducing overall system vulnerability to catastrophic failures.

AI summary
A storage system is described where goods are stored in containers and the containers are stored in stacks. Above the stacks runs a grid network of tracks on which load handling devices run. The load handling devices take containers from the stacks and deposit then at alternative locations in the stacks or deposit then at stations where goods may be picked out. The framework may be provided with one or more of the following services: power, power control, heating, lighting, cooling, sensing, and data logging. A method of partitioning the storage system prevents the spread of fire or prevent damage caused by sprinkler activation.
